CHURN.

SPECIFICATION forming part of Letters Patent No. 236,955, dated January 25, 1881.

' Application filed October 11, 1880. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL L. NELSON, of the county of Union and State of Mississippi, have invented certain new and useful Improvements in Ghurns; and I do hereby declare the following to be a full, clear, and ex act description of the-invention, such as will i enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in rotary churns; and it consists in a flat spring which is secured to the top of the frame, on top of the cover, and to the sides of the cover, and which extends down the sides of the churnbody and catches under its lower edges, whereby the cover is secured rigidly in place while the churning is being done, as will be more fully described hereinafter.

Figure 1 is a side elevation of my invention, and Fig. 2 is an edge view of the same.

A represents the cover of the churn B, the cranked operating-shaft; and O the large drivin g-wheel, which is provided with teeth around its edges upon both sides, so as to operate the two pinions D in opposite directions at the same time. This cranked operating shaft is journaled in the frame E, which is of the shape shown, and which has its lower ends turned vertically downward, so as to bear upon the top of the cover A.

Instead of the two dashers beingjournaled simply in the cover, as has generally heretofore been the case, each of the dashers is journaled upon one of the ends or branches of the U-shaped frame F, the upper ends of which frame pass up through the upper and lower ends of the dasher, through the pinions which are secured to the upper ends of the dashers, and through the frame E in which the operating-shaft is journalad. The upper ends of this U-shaped frame being secured rigidly to the horizontal portion of the frame E, the frame E is braced rigidly in position, so that no further supports or fastenings of any kind are necessary. By means of this construction it is unnecessary to fasten the frame E directly to the cover of the churn, and as this cover is divided into two parts where the dasherpinions pass through it, it will readily be seen that the cover can be readily and quickly separated from the operating parts, so that they can be thoroughly cleaned. Upon the lower end of the U-shaped frameis secured a centering -point, H, by means of which the dashers are held steadyin position.

Secured upon the top of the frame E and to opposite edges of the coverAis a Hat band or holding-rod, I, the lower ends of which are turned inward toward each other, and have a suitable amount of elasticity to hold them pressed inward against the sides of the churnbody. The lower ends of this band or rod I extend down over opposite sides of the churn, and have their lower ends to catch under the bottom of the churn, and thus hold the cover rigidly in position while the churn is in operation.

Having thus described my invention, I claim- The combination of the churn and churncover, the frame E, and the fiat band or rod I, secured to opposite edges of the churn-cover, and having its lower ends turned inward, so as to catch underneath .the bottom of the churn and hold the cover in position, substantially as described.

In testimony that I claim the foregoing I hate hereunto set my hand this 2d day of October, 1880.

SAMUEL L. NELSON.
